IBM 5160s available for local pickup only in MD until 8/20/13

by barythrin＠gmail.com

I'm reposting this for Bill since there hasn't been local interest in the last week. If you're local or near MD he's been trying to find a home for these but only has until 8/20/13. Yes we've tried to sweet talk him into shipping but he's been there and done that and is no longer interested in doing so. He can be reached on the vintage-computer.com forums. Here is his post: http://www.vintage-computer.com/vcforum/showthread.php?38549-Two-IBM-PC-XT-… "I have IBM 5160 XT's that have to go due to major downsizing. Pictures: http://www.wrljet.com/PCs/ The chassis and internal components of both are very clean. Some I have washed, some were new when installed. One cabinet is pretty good. One has some small rust spots. Both have 8087 math chips, and 640K on the motherboards. One motherboard came as a 640K, the other was 256K which I updated with bigger RAMs, added the missing mux chip, and changed the jumper. One has a single half height 360K floppy drive and working 20MB MFM hard disk. The other has two half height floppies and no hard drive. That one has a clone power supply. I think both have Mono cards, and one has a VGA. The mono and VGA don't co-exist all that politely. One has an Intel Above Board. And there's a Hercules graphics card in the box. FREE, LOCAL PICKUP ONLY in Bethesda MD USA (top of DC Beltway). These must be collected by Tuesday, 20 August to save them from the county metal/electronics recycling. Send me a private msg or email through the forum if interested. Bill " - John

cctalk Digest, Vol 120, Issue 20

by elson＠pico-systems.com

Date: Tue, 13 Aug 2013 19:53:50 -0500 From: Chris Elmquist <chrise at pobox.com> To: cctalk at classiccmp.org Subject: Re: KI front panel "VOLTAGE" adjust? Message-ID: <20130814005349.GG2148 at n0jcf.net> Content-Type: text/plain; charset=us-ascii OK. Thanks for all the input on the topic guys. It just struck me as interesting that they needed this adjustment on the front panel of the machine-- which implied that they needed to adjust it often. I guess it was a long forgotten art of making the machine easily servicable for their SEs :-) The IBM 360's (at least the mid-size and up) had voltage margin controls and a big meter on the front. Not adjusting mains voltage with a Variac, but there was a raise/lower knob and a power supply selector. The FE would run certain diagnostic loops while exercising the voltage margins. I believe the raise/lower knob ran motorized pots on the various power supplies in the back of the machine. Might have saved an hour over doing the whole procedure with a meter and screwdriver adjustment. I think that the raise/lower control was inactive unless the FE key was turned. Jon

Looking for: 4K memory board for SWTPC 6800

by derschjo＠gmail.com

Hi all -- Subject line says it all; I have 12K in my 6800 and I'd love to get up to 16K so I can use the disk system to run FLEX. I know it's possible to modify the processor board to wire in up to 8K of memory, but I'd prefer to leave it alone if possible. Anyone have a board (MP-M, MP-8M, or anything compatible, really...)? Doesn't even have to work, just be serviceable :). Thanksas always, Josh

FS: AMRAY 1610T SEM, 11/23-based EDS

by jfoust＠threedee.com

I need to dispose of the electronic microscope / spectrometer I acquired in 2001. <http://threedee.com/jmosn/microscopes/amray/index.html>http://threedee.com/jmosn/microscopes/amray/index.html http://www.labx.com/v2/adsearch/detail3.cfm?adnumb=498399 The PGT is PDP 11/23-based. If I can't find a "best offer" buyer for the entire package in the next few weeks, I'll scrap it for the metals but I'll find a classic-hearted home for the computer. Located in Jefferson, WI. - John

Sun 3/80 mobo wanted

by knowak＠alumni.calpoly.edu

By chance does anyone have a Sun 3/80 mainboard lying around. I fired mine up after years and it no longer powers up. I first thought it was the PS, but I replaced it with a known working one from an SS1 and it still was dead. Any possible ideas would be appreciated. -Kurt
